6 Claims. (01. 223-46) This invention relates to amachine for form- .ing rosettes-and. it isomer-object of the invention to provide amachinesof such construction thatqa ribbon may be applied to the machine-and engaged with pins which are then moved :transversely of the ribbon and move :portions of. the ribbon in opposite directions and form portions which are then brought together and-secured. to form loops which are spread and form av rosette having radiating arms or rays.

Another object of the invention .is to provide a rosette forming machine whichribbon-engaging pins are carried by rods 50 mounted. that they may -be.slid longitudinally andthus cause rows of pins to move in opposite directions and cause the undulations to-be all formedat the same time.

Another object-of the invention is to-so mount and arrange the pin-carrying rods that bars carrying rows ofpins will be moved in opposite directions an equal distance and thus-causercompanion portions :of undulations-formed inja ribbon to project the same distance from opposite sides of a center bar of the machine and thereby cause 'a rosette of symmetrical outline to be formed when portions of; the-undulations crossing the center bar are brought together and secured to each other.

Another object of the invention isto provide va rosette-forming machine wherein bars car-rying rods from which the pins project :have

shanks projecting from them and toothed. to

form racks which mesh withuapinion-or ,gear'so that when a handle carried by one'barcis grasped andshifted longitudinally, the twoubars will *be simultaneously moved towards 'or' away; from each other according .to the direction in which the handle istmoved.

Another object of theiinvention is to provide a rosette-forming machine wherein; a machine :for

forming rosettes has associated with it an auxiliary machine by means of which rosettesihavin'g flat arms or rays may be formed instead of rosettes. having their edges disposed against a surface to be-ornamented.

Another object of theinvention is to provide a rosette-forming machine which is of light 2 scale taken longitudinally through the .machine along the line 33 of Figure 1;

blocks being held in place by screws 9 which pass upwardly through them and into the crossbar.

Since the strip is spaced downwardly from the cross bar, there is space to accommodate a gear or pinion In which has its shaft ll rotatably mounted in a socket I2 formed in the cross bar and an opening [3 formed through .the strip. Therefore, the strip serves as a bearing for the gear and as a guide for rack bars l4 and I5 and holds the teeth of the rack bars in mesh with the teeth of thegear, as shown in Figure .4. The rack bars carry cross heads or bars I 6 and I1 and from these cross heads project rods or handles I8 and t9 which extend towards opposite ends of the frame and slidably pass through openings 20 and 2| formed through the end bars -4 and 5 and at all times project outwardly therefrom, as shownin Figure 3. One of the rods or handles has been shown provided with a knob by means of which it may be readily grasped and shifted longitudinally, it being understood that the other rod may also be provided with a similar knob, if so desired.

When the rod I8 is; grasped by itsaknob; and

drawn outwardly, the gear is rotated by action of the rack bar l4 and as the gear turns the rack bar l5 will be shifted longitudinally. Therefore, the two cross heads or bars [6 and I! will be shifted away from each other when the rod I8 is drawn outwardl and when this handle is shifted inwardly, the cross heads will be moved towards each other and simultaneously make contact with opposite side faces of the cross bar 6. Rods 23 which are mounted longitudinally of the frame I in spaced parallel relation to the side walls pass through openings 24 formed through the cross heads and prevent tilting of the cross heads transversely of the frame.

In order to form undulations or folds in a ribbon, there have been provided pins 24 and 25 formed by upwardly bent end portions of rods 26 and 27 which are passed through openings 28 formed in bosses 29 projecting upwardly from the cross heads and carrying set screws 30 which engage in selected notches 3| and secure the rods and cause the pins to move with the cross heads. Since the notches are spaced from each other longitudinally of the rods, the rods may be shifted longitudinally to adjusted positions and releasably secured in set positions. Notches or grooves 32 are formed across the upper surface of the cross bar 6 to receive portions of the rods, and upon referring to Figure 3, it will be seen that portions of the rods may also rest upon the cross heads between their upwardly projecting bosses. The pins 24 and the pins 25 are in staggered relation to each other and when the cross heads are moved away from each other they exert pull upon longitudinally spaced portions of a ribbon 33 and form undulations or loops 34 in the ribbon. Since thecross heads move simultaneously in opposite directions, the undulations or loops will be of an even length.

After the undulations have been formed, portions of the ribbon midway the pins 24 and 25 ma be grasped and brought together as the undulations are lifted from the pins and sewed 'orotherwise secured in contact with each other. The" loops 35 formed by the secured undulations 'may then be spread to form a circular rosette 36 shown in Figure 7 which is of true circular shape and has its loops or arms 35 extending radially from the center of the rosette. It will be understood that by properly adjusting the pins, undulations of varying length may be formed and a rosette formed which is elliptical or other shape. The loops 35 are so disposed that edges of the portions of the ribbon forming them are presented towards a person viewing the rosette.

In order to form a rosette having loops having flat surfaces presented towards a person looking atth rosette, there has been provided an auxiliary rosette-forming device shown attached to the frame I in Figurel and illustrated in detail in Figures 9, 10 and 11. This auxiliary rosetteforming device has a shaft 31 which is rotatably mounted through the arms 38 of a yoke'39 having a shank 40 projecting rearwardly therefrom midway its length. The yoke and its shank may be formed from two strips of sheet metal or from a single strip doubled to form the shank and having its end portions then bent to form the yoke and its arms. The shank is welded, riveted, or otherwise secured to an end wall of the frame I and projects forwardly from the frame a sufiicient distance to allow the crank handle M of th shaft 31 to be readily turned and impart rotary movement to the shaft. The end portion .'of the shaft opposite fromits crank handle is 4 threaded and screwed into a socket 42 formed in a boss midway the length of a cross head 44. This cross head is formed of sheet metal and has side edge portions bent rearwardly to form flanges 45 in rear edges of which notches 46 are formed.

Fingers 41 project forwardly from the cross head with their rear or inner ends passing through slots 48 formed in opposite end portions of the cross head longitudinally thereof and the rear ends of the fingers carry nuts 49 which confront front and rear surfaces of the cross head, but are spaced from each other a sufficient distance to allow the fingers to be slid along the cross head to adjusted positions and thus disposed in desired spaced relation to each other. The fingers are of tubular formation and through each passes a pin 50 having a head 5| at its outer or front end of such size that it may enter th finger. The pins are of such length that they pro- J'ect from rear ends of the fingers and are passed through abutment strips 52 which extend transversely across the cross head and have ends bent to form tongues 53 which project forwardly and have overlapping engagement with the side flanges of the cross head.

A head 54 at the rear end of the pin holds the cross strip thereon. At its ends, each cross strip is formed with forwardly projecting teeth 55 for fitting into the notches 46 of the flanges 45 and in order to yieldably hold the teeth in the notches, each finger has disposed therein a spring 56 which is coiled about the pin and has its front end bearing against the head 59 of the pin and its rear end in abutting engagement with the rear end of the finger with a portion projecting inwardly thereof. By grasping the cross strips and drawing them rearwardly, the teeth will be dis lodged from the notches 46 and the fingers may then be shifted longitudinally of the cross head to adjusted positions where they will beheld when the cross strips are released and return to their normal position.

When the shaft 37 is turned, the cross head will be turned with it and a ribbon will be coiled about the fingers with portions extending longitudinally of the cross head between the fingers. This will form a desired number of loops which are pinched together midway the fingers and then spread to form the rosette 5'! of Figure 12 having radially extending arms or rays 58. These rays or arms have their fiat surfaces disposed in position to be seen by a person looking at the rosette and portions of the ribbon which cross each other at the center of the rosette may be secured against each other by an ornamental fastener 59, by stitches, or in any other manner desired.

From the foregoing description of the construction of my improved machine for forming rosettes, the operation thereof will be readily understood and it will be seen that I have provided a comparatively simple, inexpensive and efilcient means for carrying out the various objects of theinvention. A

While I have particularly described the elements best adapted to perform the functions set forth, it is apparent that various change in form, proportion and in the minor details of construction may be resorted to, without departi-ng from the spirit or sacrificing any of the principles of the invention.
